TheT9 Northern Line is a commuter rail service operated bySydney Trains, serving theNorthern and parts of theInner West suburbs ofSydney.

Since 2019 the line has been numbered T9 and is coloured red on maps and wayfinding information.

The traditional Northern Line was the suburban portion of theMain North railway line (Strathfield - Hornsby) which opened in 1886 and was electrified in 1926.^[1] When theSydney Harbour Bridge was opened, it connected railway services from the Main North line and the City underground onto the North Shore line.

Passenger services used to operate as the Main North Line (same name as the physical railway line) and was colour coded red on railway maps. It operated all the way toCowan, until the service was truncated to Berowra in January 1992.^[2][3] The service, along with the North Shore Line service (yellow), later also ran along theNorth Shore railway line towards the City via the Harbour Bridge, forming a continuous loop via Strathfield, Epping and back to Hornsby.^[4]

In later years, the line operated as the Northern Line and ran from Hornsby to North Sydney via Strathfield and the City, with the North Shore line replacing services between Hornsby and Berowra. In February 2009, the Epping to Chatswood rail link was opened. In October 2009, the Northern Line service was integrated with the shuttle service betweenEpping and Chatswood. As a result, the traditional Northern Line was split in two, with trains from north of Epping operating via the new link, approaching the city via the North Shore Line and rejoining the traditional route before terminating at Epping.

In October 2013, the Northern Line, North Shore Line and Western line were merged to form the T1 North Shore, Northern & Western Line, which was colour coded yellow.

On weekdays, trains from the upper Northern Line (Hornsby via Macquarie University) joined up with the Western Line trains towards Richmond or Emu Plains, while trains from the lower Northern Line (Epping via Strathfield) joined up with the North Shore Line trains towards Hornsby or Berowra. On weekends, trains ran similar to prior to merger, where the lower Northern Line trains from Epping continue onto the upper Northern Line trains at Chatswood into Hornsby via Macquarie University.

In September 2018, the Epping to Chatswood line closed in order to be converted to metro standards as part of theSydney Metro Northwest project. As a result, the traditional Northern line branch from Hornsby to Central via Strathfield was reinstated.^[5]

On 28 April 2019, as part of the integration with theSydney Metro Northwest, the Northern Line branch was spin-off from the T1 Line and became a separate T9 Northern Line, though using the same rolling stock.^[6][7] The new line runs from Hornsby to Gordon via Strathfield (and vice-versa). The separated line runs a similar route to the pre-2009 incarnation of the line. It is also similarly colour-coded red.

The line begins at Hornsby - a junction station with the North Shore Line. The line heads south to Strathfield via Epping using the Main North Line, crossing theParramatta River between Rhodes and Meadowbank. At Strathfield, trains usually head onto a flyover over the 'Main lines', before heading east onto the Main Suburban Railway, usually using the middle 'Suburban' pair of the six tracks between Redfern and Strathfield. Trains pass through Redfern and Central, then through the western limb of theCity Circle before heading across the Harbour Bridge. Trains then head north along theNorth Shore towards Gordon, where they usually terminate. Some services continue as T1 North Shore line trains (to Hornsby or Berowra).

For off-peak and weekend services, the T9 generally runs from Hornsby to Gordon via Epping, Strathfield and the North Shore. However, the route is split into two distinct stopping patterns during the morning and afternoon peak:

Anti-clockwise direction:

• All stations from Hornsby to Epping, then Eastwood, West Ryde, Meadowbank, Rhodes, Strathfield, Burwood and then finally terminating at Central (Grand Concourse).
• All stations from Epping to Strathfield, then Redfern, Central, then all stations to Gordon, then all stations to Hornsby or Berowra (continuing as T1 North Shore line).

Clockwise direction:

• All stations from Gordon to Redfern, then Strathfield, and then all stations to Epping.
• Central (Grand Concourse), then Burwood, Strathfield, Rhodes, Meadowbank, West Ryde, Eastwood, Epping, and then all stations to Hornsby.
